Application filed April 8,

Be it known that l, dome A. STACKHOUSE, a citizen of the United States, residing at Dover, in the county of Morris and State of New Jersey, have invented a new and useful Vehicle Attachment, of which the following is a specification.

This invention aims to provide novel means whereby when the wheels of a vehicle are slipping, on the ice, or elsewhere, the

vehicle may nevertheless be propelled.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of-that type to which the invention appertains.

Although the preferred embodiment of the invention has been shown, a mechanic,

* working within the scope of the claims, may

make changes in the form delineated, without departing from the spirit of the invention.

In the drawings :'-Figure 1 shows in side elevation, a motor vehicle equipped with the attachment forming the subject matter of thisapplication; Figure 2 is a top plan.

of the structure shown in Figure 1; Figure 3 is a plan of the support and parts carried thereby; Figure 4 is an elevation of the support; Figure 5 is a section thro gh the an support and parts associated therewith; Fig ure 6 is an elevation showing the fulcrum bracket.

The numeral 1 marks a motor vehicle of any kind the chassis being denoted by the numeral 2 the running-board by the nu meral 30, the rear axle casing bythe numeral 3, and the power-driven rear wheels by the numeral 4.

In carrying out the invention, there is provided a frame 5 which operates like a radius arm, the frame comprising a cross bar 6 having angular fingers 7, arms 8 projecting from the cross bar, the arms being connected by a brace 9. The upper ends of the arms 46 8 are pivoted at 10 to the chassis 2, or elsewhere, and thus, the frame or radius arm 5 may be swung upwardly or downwardly.

The rear endof a link 11 is pivoted at 12 to the intermediate portion of the bar 6 and is pivoted at 14, at its forward end, to the intermediate portion of a lever 15, the lever being fulcrumed at 16, at one end, on a lug 17 formed on the member 18 of a clamp 19, the clamp including a member 20, the memwill advance the vehicle.

hers 13 and 29 of the clamp being con nected by securing elements 21, the clamp thus being held on the rear axle casing 3;

The lever 15' strings horizontally and the outer end of the lever is pivoted at 4'4 to a forwardly extended connectionor rod 22, pivoted at 42 to a lever 23 fulcru-med on any accessible part of the vehicle. The lever 23 has a latch mechanism 25 adapted to cooperate with the segment 24. If desired, the rear part of the segment may be colored white as indicated at 26, the forward portion of the segment being colored red, as

ends of a roller 39 journaled on the-shaft 35,

the roller 39 having ribs 40, or other traction elements. The roller 39 may be allude to as a rotatable traction member. I Y

' When the parts are ,arranged'asshown in Figure 1, the lever 23 is swung until the latch mechanism 25 is engaged with the red part 27 of the segment 24, the coloring of the segment in different hues serving as a guide for the operator, the lever 23 imparting movement to the connection 22,

the lever 15 swin in on its fulcrum 16, and the link 11 swinging the frame 6 on its pivotal supports 10, until the rollers 36 bear against the wheels 4 of the vehicle. suming thatthe wheels 4, are rotating, and slipping on the ice, the wheels .will rotate the rollers 36, the gear wheels 37 and the pinions 38 will rotate the rollers 39, and the ribs 40, engaging the ice orthe ground,

The supports 31 may be adjusted on the fingers 17 to enable the rollers 36 and 39 to cooperate,-respectively, with the wheel of the vehicle, and with the ground. The more that the lever 23 is swung in the directionof the arrow A in Fi re 1, the harder will the roller 36 be crow ed a ainst vthe ground wheel, and the more e ective Theroller 36 has gear wheels 37 ion will be the drive imported from the Wheel of the vehicle to the roller 36 endyconse'quen tly to the ground-engaging roller 39.
